GEORGE THOMAS FIELDING, JR, OF NEW YORK, N. Y.

DISSOLVINGr-VIEW DISPLAY APPARATUS.

To all whom it may concern:

Be it known that I, Gnome THOMAS FIELDING, Jr., a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Dissolving-View Display Apparatus, of which the following is a full, clear, and exact description.

The invention relates to electrically-controlled changeable exhibitingapparatus, and its object is to provide a new and improved dissolving view display apparatus, in which the display matter gradually appears and disappears to produce a highly interesting effect to the onlooker. For the purpose mentioned use is made of a casing provided with a screen and a transparent sign within the casing in the rear of the screen, two sources of light, one inside the casing and one exterior thereof for illuminating the said sign and the said screen, and means for gradually dimming one source of light while brightening the other and vice versa.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a perspective view of the apparatus, showing the door of the casing open and part of the casing in section; Fig. 2 is a transverse section of the same; Fig. 3 is a sectional plan view of the same on the line 3+3 of-Fig. 2; Fig. 4 is a like view of the same on the line 14 of Fig. 2; and Fig. 5

I is a perspective view of the motor and driving mechanism for the endless sign and the means for operating the dimming device for the electric lamps used for illuminating purposes.

As shown in the drawings, a suitably constructed casing A is provided on opposite sides with openings B, each covered by a screen C adapted to be illuminated from the outside of the casing by a source of light, preferably in the form of electric lamps D attached to the corresponding side of the casing near the top thereof. Over each set of lamps D, at one side of the casing A, is arranged a reflector E secured to the casing and serving to throw the rays of light of the lamps D down onto the screen 0 at the outer face thereof. The screen C is preferably painted with a desired subject matter,

ranged a transparent sign G, which may be fixed but is preferably in the form of an endless transparent web provided with the matter to be displayed in conjunction with the article represented on the screen C. Thus the transparent sign G may be pro vided with a representation of cigars intended to appear in the empty cigar box. The transparent sign G is illuminated from within the casing A by a source of light. preferably in the form of electric lamps Il, secured to a top partition A arranged in the casing A. The transparent sign G when in the form of an endless traveling web passes over rollers I, I, I and I jour naled in the casing A, the rollers I and I belng preferably mounted on the under side of the partition A while the rollers I I" are journaled in the bottom of the casing A. The rollers I and I are disposed opposite each other at one side of the casing so that the sign G is stretched in close proximity to the screen F on one side of the easing, and the rollers I and I are simultaneously disposed near the opposite side of the casing A to hold a portion of the sign G stretched in the rear of the screen F held at this side of thecasing. A partition A is arranged above the rollers I and I and supports a motor J for imparting an intermittent turning motion to the rollers I? and I by the means hereinafter more fully described.

The sets of electric lamps D and H are arranged in an electric circuit K, connected with a suitable source of electrical energy L, and in the'said circuit K is arranged a resistance N having a number of contact points N adapted to be engaged by a contact armQ extending from a shaft 0' inter.- mittently driven from the motor J. On the motor shaft J is secured a pinion P in mesh with a gear wheel P secured on a shaft P provided with a mutilated gear wheel Q in mesh with a gear wheel Q secured on a shaft Q carrying a sprocket wheel Q around which passes a sprocket chain Q, also passing around a sprocket wheel Q secured on the shaft I of the .roller P. The shaft I of the roller 1 is partition A.

provided with a sprocket Wheel 1 connected by a sprocket chain I with a sprocket wheel I secured on the shaftof the roller 1, so that when the motor J is running an intermittent rotary motion is transmitted by the gearing described to the rollers l and I, to impart an intermittent traveling motionto the endless transparent sign G. On the shaft 1 is secured a mutilated wheel R in mesh with a gear wheel R secured on the shaft 0 carrying the contact arm 0 for the resistance N, and when the motor J is running the said arm 0 is intermittently swung around to make contact with the contact points N of the resistance N. When the arm 0 is in the position shown in Fig. 5 the electric lamps H are burning brightly while the electric lamps D are dimmed to the utmost, and consequently the sign G is illuminated from the inside 01' the casing while the screen (1 is very dimly illuminated by the lamps 1). Now as the arm 0 travels in the direction of the arrow a the lamps H are gradually dimmed while the lamps D are gradually brightened, and when the arm 0 has made a halt revolution the lamps D are burning brightly while the lamps H are dimmed to the utmost. When" this takes place the screen C is illuminated by the rays or" light from the lamps D while the sign G is very dimly illuminated from the lamps H, and during this time airaveling motion is given to the sign G by the transmitting mechanism connecting the motor J by way of the mutilated gear wheel Qv with the driving mechanism for the rollers l and 1. During the next half revolution of the arm 0 the electric lamps D are gradually dimmed while the electric lamps H are brightened, and when the arm 0 has returned to the position shown in Fig. 5 the lamps H are burning brightly while the lamps D are dimmed to the utmost.

As shown in Fig. 2, the partitions A and A are provided withslots A A for the passage of the endless transparent sign G, which latter can fold in a chamber A arranged in the top of the casing A above the The casing A is provided with suitable doors A at the ends, for gaining access to the interior of the casing and the parts contained therein, for repairs or other purposes. I

By using the screen F intermediate the outer screen C and the sign G, it is possible to place the-parts close together without danger of disclosing the display matter on the sign G at the time the lamps D are burning brightest and the lamps H are dimmed, and consequently the display matter on the sign Gis not visible to the onlookers.

It is understood that when the apparatus is in use, anintermittent traveling motion is given to the sign G in such a manner that it is at rest during the time the lamps H are burning brightly while the lamps D are dimmed and the sign G is in motion at the time the lamps H are dimmed and the lamps D are burning brightly.

In case the screen C is provided with the representation of a cigar box, as previously mentioned, and the pictorial illustration on the sign G of cigars is in register with the box, then the ellect is that while the lamps D are burning brightly the empty box is illuminated, and when the change in lighting takes place gradually the cigar box appears gradually dimmer while the cigars on the screen become visible and gradually brighten and the cigar box gradually disappears, until finally the cigars are visible only at the time the lights D are dim and the lights H are burning brightly. From the foregoing it will be @8811 that the two pictures gradually dissolve one into the other.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:
